Oviposition pheromones in insect vectors.

Oviposition aggregation pheromones occur in a range of insect groups including Diptera, where they mediate oviposition in four different families of disease vectors. In this paper, Philip McCall and Mary Cameron discuss the selection pressures favouring oviposition pheromones and speculate on their potential applications in disease monitoring and control.

Invasions by insect vectors of human disease.

Nonindigenous vectors that arrive, establish, and spread in new areas have fomented throughout recorded history epidemics of human diseases such as malaria, yellow fever, typhus, and plague. Although some vagile vectors, such as adults of black flies, biting midges, and tsetse flies, have dispersed into new habitats by flight or wind, human-aided transport is responsible for the arrival and spread of most invasive vectors, such as anthropophilic fleas, lice, kissing bugs, and mosquitoes. From the fifteenth century to the present, successive waves of invasion of the vector mosquitoes Aedes aegypti, the Culex pipiens Complex, and, most recently, Aedes albopictus have been facilitated by worldwide ship transport. Aircraft have been comparatively unimportant for the transport of mosquito invaders. Mosquito species that occupy transportable container habitats, such as water-holding automobile tires, have been especially successful as recent invaders. Propagule pressure, previous success, and adaptations to human habits appear to favor successful invasions by vectors.

An improved procedure for the purification of Trypanosoma cruzi (Chagas, 1909) metacyclics from the insect vector.

We have developed an improved procedure for isolating and purifying the metacyclic trypomastigote form of Trypanosoma cruzi from infected Triatoma infestans. The procedure was simple, did not require time-consuming removal of the insect gut, and gave a good recovery of metacyclics. Purification involved centrifugal flotation of the parasites in Percoll followed by diethylaminoethyl cellulose column chromatography. The resulting purified metacyclics exhibited no loss of infectivity when assayed in mice as compared to metacyclics taken directly from the insects.
